Application filed April 29, 1924. Serial No. 709,829.

To all whomit may concern:

Be it known that I, FRANK KERBY, a

. subject of the King of Great Britain, residing at Woollahra, near Sydney, in the State of New South Wales, Commonwealth. of

- Australia, have invented certain new and useful Improvements in Motor-Car and,

of which the following which is fitted an approximately U shaped spring whose arms are substantially horizontal normally. The free ends of the arms project beyond the closing side of the door at different heights, preferably adjacentthe top and bottom-0f the lock. Between the arms of, the springs is a cam block adapted to. be rocked on a central pivot by ahand lever or push rod fixed to or integral there- I a with so asto spread the arms. In the door 1 frame in alignment with the arms in their normalposition are keepers provided with inclined faces so that on the door being forcibly closed to, or on the hand lever and cam being moved, the ends of thearms are spread and ride up the inclined faces'of the keepers and are retained on the handle being released. A wedge shaped block' on the base plate intermediate the spring arms may take into a corresponding recess between the keepers.

Preferably the inner faces of the keepers are inclined oppositely so that the :arms are held thereon without any possibility of play. To unlock the door, the hand lever is moved so that the cam spreads the arms clear of the keepers whereupon the door can be opened.

The arms may spring .to ensure quick return to thehorizontal position. a

But in order clearly understood I will refer to the acarms'8. and 9 outwardly.

be coupled with a suitable that the invention can be companying'drawings which illustrate the preferred form of my invention.

Figure 1, is apart perspective view of a door and its frame fitted with the invention, and

Figures 2 and 3 are sectional elevations on line 2-2 Figure 1 of the lock, in the closed and open positions respectively.

Thesame numerals indicate like parts throughout.

6 is the base is the U shaped spring whosev arms 8 and 9 are of increasedthickness at'the ends 10 and 11 respectively. The U shaped spring. 7- is anchored to the baseat 12, and, 13 and 11 are stops to limit the travel of the block pivoted at 16, and operated by a suitable handle 17. 18 is a dovetail shaped block intermediate the ends 10 and 11 and which fits into a corresponding recess '19 inthe keeper plate 20. 21 and 22 are the keepers with inclined faces 23 and 21 respectively, whereby thevends 10 and 11 of the U shaped spring are forced outwardly and so spring into the keepers to lockthe door. The inner faces of these keepers are also inclinedat 26 and 27 to conform to the shape or section of the ends 10 and 11 thereby allowing these ends to properly seat 15 is the cam.

plate of the lock, and 7 in the keepers tov prevent vibration. A

spring 25 may be secured. to the. cam block 15 to assist in-returning the handle 17 to its normal position. v

Doors fitted with this improved lock,. are prevented from vibrating as the spring arms Sand .9 rigidly hold their ends 10 and 11 in close contact inside the keepers. The dovetail block 18 also prevents any side play in the lock and takes up any wearor sag of the door due to the dropping of the hinges. 7

- It is obvious that instead-of one U spring, two spring arms separately anchored on the base plate may be employed.

Iclaimz-I- 1 A vehicle door lock comprising a casing havingspaced slots in the front end thereof, and also having awedge shaped block on the front end between said slots, a U shaped spring having-its ri within the icasin'g,I-an its arms extending ht portion secured through and mevable laterally in said slots,

. keepers to receive the wedge shaped ends ofthe U spring, and also' having a Wedge shaped recess between said Wedge shaped keepers, to receive the wedge shaped block, and means to spread the arms pf the U shaped spring. to unlock the door; 10

In testimony whereof I have hereunto set mv hand.

FRANK KERBY.
